Product Details

Product Description

The NFPW442-50 is a high-performance power conversion module specifically engineered for the Yokogawa STARDOM autonomous controller series. This unit provides a stabilized +5.1 VDC output, essential for energizing backplane logic and CPU operations. Designed for mission-critical industrial applications, the NFPW442-50 features robust electrical isolation and sophisticated protection circuitry to ensure system availability during voltage transients or overcurrent events.

The module is optimized for global industrial standards, accepting a wide AC input range and providing a high peak current capacity to handle the startup demands of multiple I/O modules. Its compact form factor and efficient thermal design allow for high-density installation in standard control cabinets.

Operational Applications

The NFPW442-50 is primarily utilized within the STARDOM FCN (Field Control Node) architecture. It is commonly found in upstream oil and gas wellhead control, renewable energy management systems, and water treatment facility automation where reliable logic-side power is non-negotiable for safety and data logging.

Technical FAQ

How does the overcurrent protection on the NFPW442-50 behave during a fault?The module is designed with a delayed shutdown. If the current exceeds 105% of the rated capacity, the unit will continue to provide power for approximately 4 to 14 seconds before shutting down. This prevents nuisance trips caused by momentary surges while still protecting the hardware from sustained faults.

Can this module be used in a redundant power configuration?Yes, in STARDOM FCN racks equipped with dual power slots, two NFPW442-50 units can be installed to provide a redundant power architecture, ensuring the controller remains active even if one power source or module fails.
